Bitspower D5 / MCP655 Extreme Pump Mod Top V2. Any gains?

[SlowSVT]

I have split my loop between the CPU block and the MB chipset cooler/GPU. I need (2) "Y" splitters to bring them all together to the single Swiftech 655 pump and was wondering if the Bitspower D5 / MCP655 Extreme Pump Mod Top V2 with it's dual inlet would lower the restrictions on the pump?

Impeller type pumps normally like having the intake directly in the center of the impeller but the Bitspower intake block places the auxiliary intake off to the side. From the photos its hard to tell exactly where the coolant meets the blades of the impeller but if it's offset to one side as it appears that may place an uneven load on the pump and may disturb the flow somewhat.



Has anyone have any testing experience with the multi port pump housing and can shed some light whether there is an improvement in the flow of the pump. I went to Skinnee's site and browsed the web but did not see any real test data.
